All 6000-ish of it lol. I'd been registered user for close on five years and I only made use of it for a couple more before that. But boy did Reddit help me out in a variety of ways small and big. And helped me waste time. Some would say too much time. Some would be right.
I deleted my content two and a half weeks ago in one big, automated purge and I've been waiting and watching and stamping out the occasional zombie content reappearing from the dead. I haven't seen any in a couple of days and today is a good day to die. This was much sadder than axing Twitter or Facebook (Freedom! Horrible, horrible freedom!)
I don't know how my experience with kbin will shake out, but I'm honestly looking forward to trying to contribute more and be more thoughtful, careful, interesting, in whatever ways that I can. That's the intention I'm starting with.
Alas, poor Reddit, I knew ye well-ish? It was a tough choice.
